@Phaedrux Thank you for the help. Now I run as many times as I want, even with the Input Shaping plugin. No more crashes!

@SetraX Well done !!! I screwed up with relative and absolute positioning.
M82 ... I figured out from some partfiles sets to absolute positioning
M83 ... sets the relative position as I need it ...SOLVED

@tylersuard if you send M308 S0 from the DWC console, what is the response?

@Drakat it's fins to use a common +VIN wire for the fans and hot end heaters, and also the Z probe if it is an inductive sensor that needs a VIN feed.

A common ground for the Z probe and the Z endstop is also OK.

A problem arises if the tool head board assumes that the thermistor also uses the common ground connection. In line with good practice, Duets boards use separate analog and digital grounds in order to get good signal integrity when reading the thermistors. The analog ground is called VSSA. Duets also provide a PTC fuse between VSSA and ground, because shorts between hot end heaters and thermistors are a common occurrence. So if your tool head board assumes a common ground with the thermistor, you have two choices:

Run a separate VSSA wire between the tool head and the Duet; Use the common ground and don't connect to the VSSA pin at the Duet end. You will get less accurate temperature readings and you will lose the protection of the fuse.

@benwithem thanks, I'll mark this as solved.

@kuhnikuehnast said in Duet 2 Wifi - PT100 Daughter Board and Accelerometer:

Are the pins on "top" of the Daughter Board the same as the pins on the Duet 2 Board?

No, the CS3/CS4 pins on the bottom of the daughter board are routed to the positions above the CS1/CS2 pins. This is what lets you stack two daughter boards. So you can wire the accelerometer as if you were plugging the cable directly into the daughterboard connector on the Duet, but if you are plugging it on top of one daughter board then configure it to use CS3/4 instead of CS1/2.

@superkevdogg driver 3 and 4 Step/Dir signals do not share a common buffer IC but 2 and 3 or 4 and 5 do.

Those buffers provide some protection but maybe you fed VMOT into them?

@Milicig please send a clear picture of the board.

@RockB said in NPN Inductive Proximity Sensor as an axis End Stop:

Just to confirm, only one pin (io[#].in) is used out of the 5 pin IOs.

Yes, that's correct. You can still use the other pins on the io connector if you want/need.

When connecting sensor (+) and GND to PSU, it should be the same PSU powering the VIN in duet right? to maintain common GND

Yes, or if using a separate PSU, tie the PSU GNDs together. You could connect the sensor positive to V_FUSED from an unused heater output, or from the fan power jumper selector (if accessible) or a fan header (with fan selector on V_FUSED) assuming the probe doesn't draw much current (please check first!), which would offer a bit of protection with the fuse. You can connect GND to the ground pin on the IO connector.

@Phaedrux 🙂
Thanks dude .

@droftarts

Awesome, thank you very much!

@vijays said in Duet3D Board to SBC (Raspberry Pi/Pico) to Galvo drivers:

Sure. I will explore on the Duet3Expansion and with RpiBuild. I think then Duet3Expansion boards works only CAN ports.. Isn't it??

Yes, the expansion boards communicate with the main board via CAN. As the Duet firmware is already set up to send movement commands over CAN, an expansion board with suitable firmware could translate those commands to DAC inputs to drive the galvo.

I think there was some early planning on how best to handle these situations. Maybe @T3P3Tony can say more?

@achrn I'm glad it's working for you. If the thermistor in the PINDA is a 100K thermistor, then at the range of temperatures that the probe is likely to experience, the difference between VSSA and GND wont make much difference. There would be a greater error at higher temperatures.

@jay_s_uk Ok swell, i'll check that out, thx.

Is the BLtouch wiring running next to the motor wiring?

@DIY-O-Sphere It's working! I went to take a picture of my jumper set-up and accidentally "nudged" the cable connecting the 5V pin and PS_ON pin. My PSU turned on... I can now turn it on and off my PSU with M80 and M81 commands. I will double check the connections next time. Thanks a lot for your help, will mark this as resolved.
